Dust is an open source of pollution due to dust on the ground, human-driven and driven to fly into the atmosphere, and is an important part of the total ambient air. Suspended particulate matter in the ambient air lasts for a long time and can be inhaled. Once the inhalable particulate enters the human body, it will accumulate in the respiratory system and cause many diseases, which is harmful to human beings. Dust monitoring is a real-time on-line monitoring measure to prevent and control air pollution. The dust monitoring equipment can monitor the atmospheric particulate matter concentration, PM value, temperature, humidity, wind speed, wind direction and other data in real time, and the dust pollution can be prevented and rectified in time by means of real-time data monitoring and alarm. The online monitoring system can save a lot of manpower and material resources and provide quantitative data support for on-site treatment and administrative enforcement. After the online monitoring system is installed, continuous and uninterrupted monitoring will be carried out. It mainly monitors respirable particulate matter and is complemented by a video monitoring system, a noise monitoring system, a meteorological system, a data acquisition system, and a communication system. The online automatic monitoring system is mainly used for online dust, environmental protection, meteorological station, tunnel and other online dust monitoring, unorganized smoke and dust pollution source emissions, residential areas, commercial areas, road traffic, construction areas, etc.; online real-time automatic monitoring of ambient air quality, and can obtain evidence through the camera. The real-time data from the weather station monitoring and the tunnel subway station can be transmitted to the data platform in time through the wired or wireless network for easy management and control. System Components The system consists of a data collector, a sensor, a video monitoring system (optional), a wireless transmission system, a background data processing system and an information monitoring management platform. The monitoring sub-station integrates various functions such as atmospheric PM1.0, PM2.5, PM10 monitoring, ambient temperature and humidity and wind speed and direction monitoring, noise monitoring, video surveillance (optional), etc.; the data platform is a networked platform with Internet architecture, which has the monitoring function of each sub-station and various functions such as alarm processing, recording, querying, statistics, report output, etc. of the data. The system can also be linked with various pollution control devices to achieve the purpose of automatic control. Implementation Scheme The online dust monitoring host can be developed using the FETMX6ULL-C SoM recommended by Forlinx Embedded. Hardware Design: FETMX6ULL-C SoM supports 8 x RS232/RS485/TTL and multi-channel I/O interfaces, which can be connected to dust sensors and other environmental monitoring equipment. At the same time, the industrial design enables it to operate stably in harsh outdoor environment, which ensures the reliability of the monitoring system. Network Communication: FETMX6ULL-C System on Module supports 2 x dual 100m Ethernet and standard TCP/IP and UDP protocol stacks. Monitoring data can be transmitted to the monitoring center or cloud server in real time through the network to realize remote monitoring and management. Wireless Communication: It supports 4G and WiFi wireless communication, and after a long time of stable testing, it can ensure the stable transmission of monitoring data, and even in the absence of wired network, it can also realize the online monitoring function. Screen Display: FETMX6ULL-C supports a variety of LCD screen designs, which enables the monitoring system to select the appropriate display screen according to actual needs, and realize the intuitive display and operation of data. Based on the features of Forlinx Embedded FETMX6ULL-C SoM, the dust online monitoring realization solution can achieve the advantages of rich hardware interfaces, stable network communication, flexible software support, etc. It is suitable for a variety of environmental monitoring scenarios and can meet the needs of the industrial level to guarantee the stability and reliability of the monitoring system.

The pollutants produced by human activities are the main factors causing water pollution. To protect the water environment, we must strengthen the monitoring of sewage discharge, the analysis of surface water, groundwater, industrial wastewater, and other water quality, and ensure the safety of people's water use. Drinking water safety concerns everybody, but many people still do not know its quality. Does the residual chlorine exceed the standard? What is the pH? These important indicators related to drinking water health need to be accurately detected. A water quality detector is a professional instrument used to analyze the content of water quality components, which can measure BOD, COD, ammonia nitrogen, total phosphorus, total nitrogen, turbidity, pH, and dissolved oxygen in water. It plays an important role and has been widely used in water quality detection and water resources protection. FETMX6ULL-C arm core board launched by Forlinx Embedded can be effectively used in water quality detectors to help us better protect drinking water. FETMX6ULL-C core board is a processor-based NXP i.MX6ULL is designed with a low-power ARM Cortex-A7 architecture that runs at speeds up to 800MHz. A low main frequency can reduce the heat generated by the CPU and extend the service life of the CPU. Its stable performance has been verified in long-term use in many fields. FETMX6ULL-C SoM is highly integrated and supports 8x serial ports, 2x network ports, and 2x CAN. The rich interfaces can connect dissolved oxygen sensors (with temperature), pH sensors, conductivity sensors, turbidity sensors, ammonia nitrogen analyzers, total organic carbon analyzers TOC, etc., to facilitate on-site construction and assembly. Dual-lane Ethernet can achieve dual-network redundancy. The 10M/100M adaptive Ethernet interface provides double insurance for the network. The support of WiFi and 4G also makes operation and maintenance more convenient. The software system uses Linux 4.1.15 and has an experienced technical support team to solve problems in the user design, allowing customers to quickly enter the product testing phase.
